ROTOR, ROTARY ELECTRIC MACHINE, AND VEHICLE

A rotor including a rotor core and magnetic pole parts provided therein is provided. The magnetic pole parts are lined up along an outer circumferential surface of the rotor core. Each magnetic pole part includes a fixed magnetic-force magnet with a radially-oriented magnetizing direction, first variable magnetic-force magnets with circumferentially-oriented magnetizing directions, a first cavity part formed in the rotor core to extend between a position radially inward of the fixed magnetic-force magnet and a position radially inward of the first variable magnetic-force magnet, and auxiliary fixed magnetic-force magnets disposed on both sides of the fixed magnetic-force magnet in a circumferential direction so that magnetizing directions thereof are oriented in the circumferential direction. A pole surface with the same polarity as a pole surface facing radially outward of the fixed magnetic-force magnet is located on a fixed magnetic-force magnet side of the auxiliary fixed magnetic-force magnets.
